Also, last Friday a cardiologist flew all the way from USA to chat to me about this work and the possibility of further applications. I wonder where this will go next?

A new application has been released by Dr Peter Bentley of the Digital Biology Group in UCL Computer Science (and author of The Undercover Scientist, recently published in paperback). The "iStethoscope" turns the phone into a very effective digital stethoscope by amplifying and filtering the audio in real time (and analysing it with a spectrogram display). The free version was available for 10 months and had several million downloads worldwide. This led to several cardiologists getting in touch, and to international collaborations and the release of a professional version of the application. There is now a medical trial underway. Users are able to email their heart audio direct to a laboratory where the data are analysed and used to build an automatic diagnosis system. Other medical applications are under development.

One of my old students Udi Schlessinger gave me a mention in his blog.

My cardiologist collaborator Glenn Nordehn tells me we are gathering a nice collection of heart sounds from the app which he will make available as an online resource soon. He also said:

I showed iStethoscope Pro to a group of students today. When I walked around the room with the spectrogram . . . they were amazed.

And finally Apple finally approved the latest update 1.02 which includes those two often- requested features: a button to switch to the graph mode (touch the stethoscope image) and the ability to ignore the last 1 second of audio.

As usual if you have comments or queries about the app, please go to the support page.

Dear Mr Peter J Bentley.

How do you do?. I'm Japanese、 living in Japan. I love read and watch your book(The book of numbers) The book has many episode lots of pictures. Manyinteresting story in the book. That is great. The book is my No1 favorite! I love "NUMBERS" and history of numbers. I'm really interesting in numbers.

First I had interesting in the Numerology. The Numerology fascinate me soon. Then I'm interesting in religious of history、 tarot and math. The numbers are very close to us. I read your postscript of the book. I would to tell you "my find out of numbers". If you still know the my find out of numbers story、 I'm sorry. also my english is not good...like a puzzle. I'm so sorry too.

I had interesting in AMICABLE NUMBERS(PAIR)

"THE AMICABLE PAIR IS PERFECT PERTNER OF DESTINED TO BECAME TOGETHFR"

I think 、it's very romantic. Then I want to know "The chemistry of amicable pair(each other)" Then I checked the amicable pair.

(my find out)

[a numerology rule]

ex) 220 : 2+2+0 =4

284 : 2+8+4=14 1+4=5

Single figures(1〜9)

ex) 220 284 =4 5

I checked for 100 of amicable pair from smaller.

So Single figures、

1,8 (also 8 ,1)= 23

2,7　　　 　　 = 33

4,5　　　 　　 = 26

9,9　　　 　　 = 14

￣￣

96

(others)

3,6 = 1

6,9 = 2

6,6 = 1

￣￣

4

1〜9 pair = 45patterns.

BUT Almost pair are 4pattern. 96/100

AND

1+8= 9

2+7= 9

4+5= 9

9+9=18 1+8= 9

3+6= 9

6+9=15 1+5= 6

6+6=12 1+2= 3

5/7 = became 9

7/7 = multiples of 3

AND

Become the even number when add bottom one column of the odd pair.

ex) 12285 , 14595

5+5=10

ex) 69615, 87633

5+3=8

AMICABLE PAIR in Japanese = 友愛数。

友=Friend、 愛=Love、数=Number.

SO I think、 AMICABLE PAIR(NUMBER) become the even number divisible peacefully.

They are so lovely. I want to share the lovely story with you. NUMBERS SO INTERESTING AND BEAUTIFUL. Thank you very much.
